The Aeolian archipelago, a UNESCO World Heritage site since 2000, off the north-eastern coast of Sicily, is made up of 7 islands: wild Alicudi and Filicudi, worldly Panarea, Salina, the green island, Lipari, the largest and most populated, Vulcano and Stromboli with their active volcanos. Black sands, craters, pumice and obsidian quarries, sulphur mud baths and hot springs are a testament to the archipelago's volcanic origins. The thousand year old history of the islands is well documented in Lipari's Archaeological Museum. Lipari, the heart of the archipelago, offers restaurants, shops, cafés and bars as well as enchanting beaches such as those of Canneto, Vinci and the bay of Spiagge Bianche. Salina, the most fertile of the islands is renowned for its capers and Malvasia wine and, with its rocky seabed, cliffs, grottoes and coves, is a paradise for scuba diving. The bay of Pollara, the setting for Troisi's "Il Postino" is certainly worth a visit. Mount Fossa delle Felci is ideal for hikers. Spectacular Stromboli is the only island with a continuously active volcano with frequent and regular explosions of lava stone and magma that flows down the "Sciara del fuoco" to the sea. An excursion to the crater is a unique experience and well worth the three hour walk. The Aeolian islands can be reached by ferry or hydrofoil from the ports of Milazzo, Messina, Reggio Calabria, Naples and Palermo.
